Marine geology datasets from Centre for Estuarine and Marine Ecology (NIOO-CEME)

The National Oceanographic Data Committee (NODC) of the Netherlands is the national platform for exchange of oceanographic and marine data and information, and for advisory services in the field of ocean and marine data management. The overall objective of the NODC is to effect a major and significant improvement in the overview and access to marine and oceanographic data and data-products from government and research institutes in the Netherlands. This is not done alone and only with a national focus, but on a European scale as an active partner in the Pan-European SeaDataNet project, complying to the INSPIRE and the new Marine Strategy EU Directives, and on a global scale as the Netherlands representative in major international organisations in this field, ICES and IOC-IODE. A major step has been made with the launch of the NODCi - National Infrastructure for access to Oceanographic and Marine Data and Information. This was developed in the framework of the Ruimte voor Geo-Informatie (RGI) programme as RGI-014 project. It includes a new NODC-i portal (www.nodc.nl), that provides users with a range of metadata services and a unique interface to the data management systems of each of the NODC members. By this Common Data Index (CDI) interface, users can get harmonised access to the datasets, that are managed in a distributed way at each of the NODC members. The NODCi portal functions as the Dutch node in the SeaDataNet infrastructure. The NODC CDI service contains several thousands of references to individual marine and oceanographic datasets. For inclusion in the National Geo Register these have been aggregated by combinations of Data Holding Centres - Disciplines. Each NGR - NODC record therefore represents a large number of individual metadata records and associated datasets. By following the specified URL to the NODCi portal, users can consider these metadata in detail and can achieve downloading of interesting datasets via the shopping cart transaction system, that is integrated in the NODCi portal.荷兰国家海洋数据委员会（National Oceanographic Data Committee, NODC）是荷兰国内开展海洋与海事数据信息交流，以及提供海洋、海事数据管理领域咨询服务的国家级平台。 该委员会的总体目标是大幅提升荷兰政府及科研机构产出的海洋与海事数据及数据产品的可概览性与获取渠道。这一目标并非仅依托本国力量单独达成，而是以积极参与者的身份加入泛欧洲SeaDataNet项目，在欧洲层面开展合作，同时遵循欧盟《空间信息基础设施指令》（INSPIRE）与新版《海洋战略欧盟指令》，并在全球层面以荷兰代表的身份参与国际海洋考察理事会（International Council for the Exploration of the Sea, ICES）与联合国教科文组织政府间海洋学委员会国际海洋数据与信息交换办公室（Intergovernmental Oceanographic Commission - International Oceanographic Data and Information Exchange, IOC-IODE）等该领域的主要国际组织工作。 随着NODCi——海洋与海事数据信息获取国家基础设施——的正式上线，相关工作取得了重要进展。该设施是在地理信息空间（Ruimte voor Geo-Informatie, RGI）计划框架下的RGI-014项目中开发完成的，其搭载全新的NODCi门户网站（www.nodc.nl），可为用户提供一系列元数据服务，并为各NODC成员的数据管理系统提供统一访问接口。通过这一通用数据索引（Common Data Index, CDI）接口，用户可实现对各NODC成员分布式管理的数据集的规范化统一访问。NODCi门户网站同时作为SeaDataNet基础设施中的荷兰节点运行。 NODC的CDI服务包含数千条独立海洋与海事数据集的引用记录。为纳入国家地理注册系统（National Geo Register, NGR），这些记录已按照数据持有中心-学科组合的方式完成聚合。因此，每条NGR-NODC记录均对应大量独立元数据记录及关联数据集。用户通过访问NODCi门户网站的指定链接，可详细查阅这些元数据，并通过集成于门户网站内的购物车交易系统下载目标数据集。
